PMP Schedule Management 4

Question 1

A project manager notices that two activities on the critical path have a start-to-start dependency with a 3-day lag. If the predecessor slips by 2 days, what is the impact on the successor?

Accepted Answer

Successor slips 2 days

Answer

With a start-to-start dependency, a 2-day slip in the predecessor's start date shifts the successor's earliest start by 2 days; the lag remains constant.

Question 2

Which technique involves interviewing subject matter experts to obtain reliable duration estimates by reconciling high, low, and most-likely estimates?

Accepted Answer

Three-point estimating (PERT)

Answer

Three-point estimating (PERT) uses optimistic, pessimistic, and most-likely estimates from experts to calculate expected duration with statistical confidence.

Question 3

A project has a total float of 10 days on a non-critical activity. The project manager uses 8 days of that float. What happens to the float on subsequent activities in the same path?

Accepted Answer

Their float decreases by 8 days

Answer

Total float is shared along a path; consuming 8 days of float on one activity reduces available float for all subsequent activities on that path by the same amount.

Question 4

During Sequence Activities, the project manager identifies an activity where work can begin before its predecessor finishes. This is represented using:

Accepted Answer

Lead

Answer

Lead allows a successor activity to start before its predecessor finishes, effectively overlapping activities to shorten the schedule.

Question 5

A project manager is reviewing the schedule baseline. Which statement about the schedule baseline is correct?

Accepted Answer

It can only be changed through the integrated change control process

Answer

The schedule baseline is a formal, approved version of the schedule that can only be changed through integrated change control, not routine progress updates.
